Problems solved by technology

[0002] In the oilfield combined station, people usually use the heating furnace to heat the treatment medium to meet the needs of oilfield production, so the operating efficiency of the heating furnace has a direct impact on the energy saving and economic benefits of the oilfield combined station, for example, due to the amount of fuel and air Unreasonable ratio and other problems lead to low operating efficiency of the heating furnace and uneconomical operation

At present, the oil field joint station regularly conducts parameter adjustment and optimization analysis on the heating furnace, but often does not consider the problems of the heating furnace itself, and due to the difference in the structure and service life of the heating furnace, the scale resistance of the inner wall and the heating coil is also different. The change of the scale resistance of the heating furnace will inevitably affect the accuracy of the optimization analysis results of the entire parameter adjustment. The existing optimization analysis methods lack the reliability analysis of the heating furnace parameters, and are not specific to each heating furnace. On-site staff In the face of the above situation, even through optimization analysis, it is impossible to obtain accurate optimal fuel quantity and optimal excess air coefficient, etc.
